1c all 'whom ii may Sen-eem: ie itlmown that It, JOHN citizen of the Unitetl Stetee. Bartlesxjille, in the count-j' et vlJvvmliiiigton and State of (lklsihonia, have invented a new and useful Swivel-Senke@ of which tlie following is a specification.

invention relates to Iiiiiprovenfxente in swivel Sockets used in drilling wells with J) in which e groove, el or peritoratefl Swivel turns in the trot wliieii is pierced with slusli objeote oieniy improvement o allow Water and senil and other W 'through the swiveleocket :incl 4lille the tools are in operation; o 1 rovioe ii continuous and millemref' revo it-iori of toe swivel in the socket7 without. impetling the rotation of the tools in lie liole; and third, 'to prevent sending ,W enoumbeiing. enti obstruction on the i11- side of the socket es the swivel turns therein. atta-iii these oliieete by the mechanism illustfatecl in the aecoiiipaiiying drawing, in

Teosser., residing it ici to etioel section oit' the Fig. 2 shows a full el i and the inottom pien of v E f vertical Seetioii of' the soo .lf shows e full elevation o' li swivel, siii the eottoirl seme;

l"ofs "'eifioz. Section of the Swivel;

Seat o" the Socket to allow the water mel sami t pass out; the interior or shoulder of the barrel oF tlie socket is milled or forro/Weil witerzmd sand to flow tlii'ougli. easily; (C) is the swivel through E) the Wire line passes; (H) ifi the end View of the Swivel wherein lie knot on the end oi the line is drawn; l), D) are recesses or corrugatiois oi? grooves or holes iii the swivel to allow the water and Sand :mil other fiuiel to pees out. l

` "ging up for operation, tlie knotted enel of the Wire line or Wire cable is drawn into the sont of the swivel (H) shown in Fig. (l, it is tiren pulled in as far as possible fui-.fl driven home with a Sledge ail Suitable pin. The Swivel Wiizli the knotted Wire line passed through its bore, is then run up through the barrel of the Socket and drawn up ready for drilling.

'liie Q'roewee or ooriugations or perforations (i), l the swivel and the apertures or slush liolee B, B) in the lierrel A) and the milled or 'urroirecl Seat of tlie Socket, constitute the essence of the imprin/emeritoj for thereby7 explained above the swivel so'oliet is rendered self-oleer1ing. lt will not seid up or fail to Work :it :my time. 'lhile 'the Wall of the swivel is formed to t the Well o the socket so that the swivel will be thereby guided in .its movement, yet the grooves or channels D provie :i broken rouglienecl surface on tli swivel that will interrupt the Contact between 'the said walls and provide eoi'iduotH ing spaees or channels through which Water and santi escape. ln like manner the milled or furrow/ed on the interior of 'the shoulder of the socket at provides an terrupted conftaeting surface between 'that part the socket ami tile Swivel. also peimittiiig the @geestige or water. :mtl santi `etween the parte. The Atools rotate in one direction all the time.; this is Caused by the Weight of "alie stem ou tile-ascentizt'tei hit-- 'ting bottom taking ehe natural twist out of the line, causing tile tools to turn one Wag@ end the tools relei: on tlie descent nel on touching bottomj the swivel nets and allows the twist of the line to return to its natural condition.

am aware that. prior to my invention, swivel sockets have been made and used. therefore, (lo not claim such an appliance broadly; out

claim:

i. A Well-drilling tool having e hollow socket member aperturefl tliiougli its Well to permit the eseape of foreign matter, and e. swivel member within said socket member having its outer surface bearing against and ,gnidecloy the inner surface of the socket member :mtl having said surface roughene or broken whereby the swivel membei1 is guided by the wall of the socket member while at the same time passage-nys between the members are formed for the passage of foreign matter between the two meml'iers, substantizllly as described.

2. A welledrill tool haring an outer apertured sorket member and an inner swivel member having its exterior surface bearing against the inner face of the socket member whereby the swivel member is guided and having its surtaee exteriorly channeled to permity of the escape of foreign matter between the swivel member and the socket member, substantially as described.

il. A well-drill tool having an outer socket member apertured through the Side wall thereol, an inner rope-clamping swivel member longitudinally movable in the outer men'iber bearing against and guided by the wall thereolf and having longitudinally extending exterior channels formed on the exterior surlfaee of the swivel member, sub! stantially as described.

sli. AMeli-drill tool comprising a hollow soelet member having a Shoulder, a swivel member loosely mounted in said socket member andadapted to abut against said shoulder, said swivel member having its exterior surface in contact with and guided i by the Wall oi the said socket meunier, said surface being rougheiied or 1roken to interrupt the Contact between the members to thereby permit the passage of foreign matter between their walls, said rougliened or broken surface extending along the exterior of the swivel member beyond the point, of engagement of said member with the shoulder, substantially as described.

5. A well-drill tool having an exteriorly shouldered member, a sliding swivel member adapted to lit within said shouldered member and having means to abut against Said shoulder, Said outer member provided at said shoulder with a roughened or broken surface in contact with the :swivel member land said swivel member provided on its outer surlaee with a breken or interrupted surtaee portion adi utedvto bear against the inner surface of the socket member, said outer member having au escape aperture in its wall, substantially as described'.
